4:50 p.m.

A family representative who started a GoFund Me campaign to help cover funeral expenses of the four children killed by a felon while in a standoff with police says the mother is in a state of shock.

Walter Benenati employs the father of the woman, whom police have not identified. Benenati says she also needs to cover expenses to move out of the apartment in Orlando, Florida, where the shootings happened.

Benenati says the oldest hostage was 12-year-old Irayan. He says Irayan loved video games and was an overachiever at school. He says Lillia was a huge Disney fan and the 10-year-old enjoyed being with her friends. He says 6-year-old Aidan had a dinosaur obsession and 22-month-old Dove liked to run.

The woman was the mother of all four children. The suspect, Gary Lindsey, was the father of Aidan and Dove.

Benenati says Lindsey committed “an unspeakable horror.”

A felon who killed four children during a daylong standoff that started with the shooting of an officer was arrested last month and his probation officer recommended that he be jailed for six months.

But Gary Lindsey had supervised probation reinstated during a hearing several weeks ago.

Lindsey was sentenced to 10 years of supervised probation 10 years ago for burning his home during a dispute with his-then girlfriend.

Court records show an arrest warrant was issued for Lindsey last month for violating the terms of his probation after he was arrested for theft. A probation officer recommended that Lindsey be jailed for six months, but court records show Lindsey’s sister agreed to pay $1,000 and he agreed to pay $300 a month toward restitution. His supervised probation was reinstated.

The court records show Lindsey had been working at an auto center in Orlando.

Neighbors in the Florida apartment complex where a felon killed four children during a daylong standoff that started with the shooting of an officer described the gunman as both nice and strange.

Nicole Gonzalez said Tuesday that 35-year-old Gary Lindsey came off as polite and friendly. But another neighbor, Miguel Lopez, says interactions with him were weird.

Authorities say the convicted felon was out on probation when he shot and wounded Officer Kevin Valencia late Sunday night. Valencia was responding to a domestic violence call from Lindsey’s girlfriend. He is recovering after surgery and is expected to live.

Authorities say two of the children are believed to be Lindsey’s, while the other two are believed to be the girlfriend’s.
